OF

GEOMETRICAL CONSTRUCTIONS.

I.

2.

The following constructions are to be made with the Ruler and Compasses only; the Ruler being used for drawing and producing straight lines, the Compasses for describing circles and for the transference of distances.

The bisection of an angle.

The bisection of a straight line. 3. The drawing of a perpendicular at a point in, and

from a point outside, a given straight line, and the determination of the projection of a finite line on a

given straight line. 4. The construction of an angle equal to a given angle;

of an angle equal to the sum of two given angles, &c. 5. The drawing of a line parallel to another under

various conditions and hence the division of lines

into aliquot parts, in given ratio, &c.
6. The construction of a triangle, having given

(a) three sides;
(B) two sides and contained angle;
(y) two angles and side adjacent;

(8) two angles and side opposite.
